Bernadette Jean "Kelly" Johnson was an English guitarist and singer, widely known in the UK in the early 1980s as the lead guitarist of the all-female rock band Girlschool.

Girlschool are a British rock band that formed in the new wave of British heavy metal scene in 1978. Frequently associated with contemporaries Motörhead, they are the longest-running all-female rock band, still active after more than 40 years. Formed from a school band called Painted Lady, Girlschool enjoyed strong media exposure and commercial success in the UK in the early 1980s with three albums of "punk-tinged metal" and a few singles, but lost their momentum in the following years.
